Quantum phases of SrCu2(BO3)2 from high-pressure thermodynamics
Jing Guo, Guangyu Sun, Bowen Zhao +9
We report heat capacity measurements of SrCu(BO) under high pressure along with simulations of relevant quantum spin models and map out the phase diagram of the…

Dynamical Signature of Symmetry Fractionalization in Frustrated Magnets
Guang Yu Sun, Yan-Cheng Wang, Chen Fang +3
The nontrivialness of quantum spin liquid (QSL) typically manifests in the non-local observables that signifies their existence, however, this fact actually casts shadow on detecti…

Dynamical Signature of Fractionalization at the Deconfined Quantum Critical Point
Nvsen Ma, Guang-Yu Sun, Yi-Zhuang You +4
Deconfined quantum critical points govern continuous quantum phase transitions at which fractionalized (deconfined) degrees of freedom emerge. Here we study dynamical signatures of…
